An unmanned satellite A and a space- craft B are orbiting around the earth in same circular orbit as shown. The space-craft is ahead of satellite by some time. Let us consider that some technical problem has come in the satellite and astronaut from B has to make it correct. For this to be done Docking of two (A and B) is required ( in layman terms connecting A and B). To achieve this, rockets of A has been fired in forward direction and docking takes place as shown in figure .After once returning to the original point i.e., the place from where rockets have been fired, in which direction and with what extent the rockets have to be fired from satellite to again comeback in the original orbit? A. forward direction with same extent B. backward direction with same extent C. forward direction with higher extent D. backward direction with higher extent

To bring back the satellite in the same orbit, we have to make the speed of the satellite as initial one for which we have to increasevfvfby such amont so that it becomes equal tovivifor which we have to fire the rocket in backward direction with the same extent.

The answer is optionbackward direction with same extent
